GUS-QS8A-03-1690-DC Description

The GUS-QS8A-03-1690-DC from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 8-resistor isolated network features a 169Ω resistance value per resistor with an ultra-tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -55°C to +125°C. Packaged in a 16-pin QSOP with gull-wing terminations, it offers a compact footprint (4.9mm x 6.02mm x 1.47mm) and robust 0.75W total power rating (0.1W per resistor). Its 100V maximum voltage rating and thin-film technology make it ideal for precision analog and digital circuits.

GUS-QS8A-03-1690-DC Features

• High Precision: 0.5% tolerance and ±25ppm/°C TCR for critical signal conditioning.
• Robust Power Handling: 0.75W total (3/4W) with derating up to 125°C.
• Isolated Design (ISOL): Each resistor operates independently, reducing crosstalk.
• Compact QSOP Package: Space-saving 16-pin gull-wing SMD profile (4.9mm x 6.02mm).
• Thin-Film Technology: Superior stability and low noise vs. thick-film alternatives.
• Wide Temp Range: Reliable from -55°C to +125°C, suitable for industrial environments.
• Non-Automotive: Compliant with general-purpose electronics (PPAP not required).

GUS-QS8A-03-1690-DC Applications

• Precision Voltage Dividers: In ADC/DAC reference circuits.
• Medical Equipment: Patient monitoring systems requiring low drift.
• Test & Measurement: Calibration instruments demanding high accuracy.
• Industrial Controls: PLCs and sensor interfaces with isolated signal paths.
